LoL: INTZ e-Sports vs Vivo Keyd Stars Academy (BO3) - Circuito Desafiante Playoffs

Platform comparison

Market context

INTZ e-Sports and Vivo Keyd Stars Academy were scheduled to meet in a best-of-three upper-bracket semi-final in the Circuito Desafiante Playoffs on 24 August, with listings placing the start at 23:00 UTC and the market’s settlement window already elapsed by the stated cutoff. Public match pages indicate the series was still pending around the event time, while the prediction market itself was set up to resolve on the actual result, or 50-50 if the match was not played or ended tied.

The current 0% YES price should be read against the combination of a live esports bracket and the mechanics of on-chain settlement rather than as a pure sporting forecast. In similar match contracts, prices can flatten when the event has already passed its scheduled window or when traders expect a late schedule change, because the contract only pays out cleanly once a final result is published and accepted for resolution. Broader crypto conditions were mixed in mid-August, with BTC around the low-$60,000s and ETH near $1,800-$1,900 on recent market snapshots, while USDC stayed close to parity; that matters mainly for collateral and liquidity, not for the match outcome itself.

Traders should watch for any official bracket update, rescheduled start time, or post-match publication of results, because the market’s resolution depends on whether the series is actually played and whether a final score is recorded by the designated source. Any last-minute change to the playoff order, stream delay, or postponement beyond the permitted window would be the main catalyst for a repricing away from the current zero-odds stance.

Methodology

This page reads LoL: INTZ e-Sports vs Vivo Keyd Stars Academy (BO3) - Circuito Desafiante Playoffs on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

UK Frequently Asked Questions

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

Can I use Bitcoin directly?

No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
